Works perfectly for me with nvidia drivers 185.13 (and has done for as long as I can remember, probably back to the 169.xx series of drivers).
You must have compiz disabled though, xvideo sync NEVER works with compiz enabled even with only one monitor (I seriously hope this is something the nvidia devs are planning to fix very soon).
Opengl sync only ever works on one of the monitors if both are enabled. If only one is enabled, it works on that one. It would be nice to have an opengl monitor sync option like the xvideo sync option which decides which monitor to sync to.
